Bio-oil is produced by rapid pyrolysis with woody biomass. Bio-oil has some advantages, low reaction temperature to produce, high yield, and good transportability because of liquid. So, Bio-oil is expected as measures of global warming or securing stable supply of energy. Last year, operation test of Bio-oil was carried out at institution treating sludge in Saitama. In this result, comfirmed Bio-oil availability in place of fuel oil A without air pollutant. In this research object is to improve property of Bio-oil and to get data by operation test.
